WILLIAM LEWIS OASADAY, OF SOUTH BEND, INDIANA.

DISK PLOW.

SPECIFICATION forming part Of Letters Patent No. 625,320, dated May 23, 1899.

Application filed January 25, 1899. Serial No. 703,352. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM LE IS (JAsA- DAY, a resident of South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Disk Flows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to an improvement in disk plows, and more particularly to means for mounting a revoluble disk, the object of the invention being to so connect a disk with a plow-frame that the disk can be readily adj usted to different angles.

A further object is to provide means whereby a rotary disk can be securely mounted and at the same time permit of the ready manipulation of parts, whereby to adjust the disk to different angles.

A further object is to provide a disk plow which will be simple in construction, easy to operate, and most effectual when in use.

With these objects in View the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter de scribed, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view illustrating my improvements. Fig. 2 is a view in section of same, and Figs. 3, 4, 5, and 6 are views of details.

1 represents asection of the frame of a plow, and 2 my improved block or bracket secured thereto by suitable bolts 3. The box 2 is provided with a sleeve 4, having a conical interior. The inner wall of the sleeve 4 consists of an annular series of flat faces 5, as many of said flat faces being provided as may be desired. A sleeve 6, conical in general form, is adapted to be inserted in said sleeve 4, and the outer face of the sleeve 6 is eccentric to the axis of said sleeve, so that when placed in the sleeve 4 the axis of the two sleeves will be eccentric to each other. The eccentric sleeve 6 is provided nearone end with a series of flat peripheral faces 7, corresponding in number and form to the sleeve 4. The fiat faces 7 on the sleeve 6 are adapted to fit into the angular interior of the sleeve 4, and it will be seen that by simply removing the sleeve 6 from the sleeve 4and giving the sleeve 6 a partial turn and replacing same will give a diiferent angle to the central longitudinal line of the interior of the sleeve 6. A suitable thumb-screw b may be screwed through the sleeve 4, whereby to secure the sleeve 6 in place. The inner end of the sleeve 6 is contracted, as shown at 8, and a screw-threaded opening 9 is provided centrally in the free end of the-contracted portion of the sleeve 6, through which opening oil is fed to the spin dle or shaft 10 of the disk-holder 11, as will be more fully hereinafter described. The outer end of the sleeve 6 is provided with a peripheral flange 12 and also with a peripheral groove 13, adjacent to said flange.

The disk-holder 11, having the hollow con ical shaft or pinion 10 thereon, is disposed in the sleeve 6 and is provided in its end with a removable section a, conical in general contour and having a thrust bearing against the inner face of the contracted inner end of the sleeve 6. The section 0 is provided with a tubular extension 0, which projects into the shaft or spindle 10. The disk-holder 11 is provided around said spindle or pinion 10 with a flange l4, and the flange 12 of the sleeve 6 is disposed in and adapted to turn within said flanged portion 14. Suitable clamps 17 are disposed at diametrically opposite points on the disk-holder 11, and suitable projections 16 are provided on said diskholder to limit the movement of said clamps. The clamps 17 are made semicircular on one edge and are provided with a flange 18 around said semicircular portion which overlaps the flange on the sleeve 6 and is disposed in the groove or recess 13 in the sleeve 6, and the ends of said clamps are provided with cut-out portions to receive the projec tions 16. Each clamp 17 is provided with an outwardly-extending flat arm 18, disposed between parallel projections 19 on the diskholder 11, and said holder and arms 18 are provided with alined openings for the reception of suitable bolts 20, secured in place by nuts 21, as shown. The disk-holder 11 is provided centrally with a screw-threaded opening 22, which communicates with the interior of the spindle or shaft 10, and is adapted to receive a screw-threaded bolt 23, whereby to secure any approved disk 25 in place.

The opening 9 in the end of the sleeve 6, heretofore referred to, is adapted to receive oil, and it .will be seen that when oil is poured therein it will pass through an opening 24 in the section into the spindle 10, and said oil will be fed from the interior of the spindle to the outside thereof by centrifugal action of the revolving spindle. Any suitable plug 26 (screw-threaded, if desired) maybe inserted in the opening 9 to prevent the entrance of dust and grit to the spindle.

It will be seen from the above description that the sleeve 6 can be turned to adjust the spindle 10 therein and disk on said spindle to a great number of different angles relative to the groundas, for instance, one adjustment of the sleeve 6 will not only elevate or lower the disk and dispose the same at different angles to the ground, but at different angles and to difierent sides of the longitudinal center of the plow-frame. This is ef fected by the double eccentric formation of the devices which connect the disk with the plow-frame.

An L-shaped bracket 27 is secured to the frame 1 by any approved means and projects over the disk 25. A downwardly-extending arm 29 is adjustably connected with said arm or bracket 28 by means of a suitable coupling 30, secured againstaccidental movement by a thumb-screw 31. MyimproVed scraper 32 is secured to a support 33, which is made with an elongated curved slot 34 near its upper end for the reception of a pin 35, which projects at right angles from the arm 30, and saidpin 35 is preferably screw-threaded at its end for the reception of a thumb-nut 36, whereby to secure the support 33 and scraper 32 thereon at any desired adjustment relative to thedisk.

It will be seen that my improved scraper 32 not only acts as a scraper to clean the disk, but at the same time performs the additional function of assisting in the turning of the furrow. lVhen the disk 25 is adjusted to different angles,as heretofore described, the scraper 32 should also be adjusted relatively to said disk.

Various slight changes might be resorted to in the general form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I-would have it understood that I do not wish to limit myself to the precise details set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described myinvention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination in a disk plow, of a disk and means connected directly with the disk for simultaneously adjusting the elevation and angle of said disk by a manipulation of the disk itself.

2. The combination with a bracket, of an co I centric disk-holder adj ustablysecured thereto and a disk secured to said holder.

3. In a rotary plow, the combination with a frame, of a sleeve secured to said frame and having an angular inner face, an eccentric sleeve disposed in said first-mentioned sleeve and a spindle revolubly mounted in the cocentric sleeve and adapted to carry a disk.

4. In a plow, the combination with a frame and adisk, of devices constituting a double eccentric connecting said disk with the frame.

5. In a rotary plow, the combination with aframe, of a sleeve secured to said frame and having an angular inner" face, an eccentric sleeve disposed in said first-mentioned sleeve, a disk-holder, a spindle on said disk-holder disposed in said inner sleeve and means for revolubly securingsaid inner sleeve to the disk-holder.

6. In a rotary plow, the combination with a frame, of a block having a sleeve thereon secured to said frame, a disk-holder, a spindle on said disk-holder, disposed in said sleeve and a second sleeve between said first-mentioned sleeve and spindle whereby to adjust the angle of said disk-holder and disk thereon.

7. In a rotary plow, the combination with a frame, of a block secured to said frame and having a sleeve thereon, a second sleeve dis posed in said first=mentioned sleeve, said sec-- ond sleeve having a flange around its lower end, a disk-holder, a spindle on said disk-,

holder disposed in said second sleeve, a flange on said disk-holder to receive the flanged end of said second sleeve and clamps secured to said disk-holder and adapted to secure the second sleeve revolubly against the diskholder.

8. The combination with a plow-frame, or

a disk, means for adjusting theangle of said disk relatively to the ground, a scraper and means for adjusting the scraper so as to conform to the changed adjustable disk.

9. The combination in a plow, of a disk, means for simultaneously adjusting the elevation and angle of the disk, 2. scraper and means for adjusting the scraper relatively to said adjustable disk.

10. The combination in a plow, of an adjustable disk, a fixed bracket, a coupling adjustable on said bracket, a depending arm connected with said coupling so as to be adj ustable vertically and revolubly, a scraper being adjustably connected to said depend ing arm.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
